About Kenzie
I’m Kenzie Mosher, a Functional Diagnostic Nutrition Practitioner and fat loss coach based in Spencer, Iowa. I help women 35+ FINALLY get real answers about their weight, hormones and gut... and a clear plan for what’s next. All virtual, so it doesn’t matter where you live.
Because I’ve been there
You’re the one holding it all together. The kids, the job, the house, your marriage, everyone else’s needs... and somewhere along the way, you landed at the bottom of your own list. You’re eating well and working out. And your body still isn’t cooperating. Your gut’s a mess. Your hormones are all over the place. You’re exhausted and wondering if this is just how it’s going to be.
I know that place, because I lived there for years.
01
I’ve spent over 20 years in health and fitness. I owned a dance studio with four locations, then two functional fitness gyms with my husband [my #1 guy], all while coaching women on nutrition and raising two busy kids. I was the Type A perfectionist and people-pleaser who worked all the time. No balance. No self-care. A lot of chaos.
02
Then 2017 hit. My husband lost his job. We lost a pregnancy. My brother was tragically killed at 19 and the grief hit hard.
Then I found out my breast implants were making me sick... I felt like I was dying. So I had surgery to have them removed.
But old habits die hard. I kept hustling, running two full-time businesses, until I was completely burned out. My husband and I made the hard decision to walk away from the gym. Two months later, I had a hysterectomy at 38... which brought a whole new set of hormone changes and 20 extra pounds. All of that on top of 20+ years of gut issues, anxiety and depression.
03
Maybe this part sounds familiar. I was eating well, working out and finally slowing down for once in my life. And I still didn’t feel like me.
Looking back, my stress bucket had been overflowing for years. The losses, the hustle, the busy schedules, the pressure to hold it all together... it all adds up. Your body can handle a lot. But when that bucket overflows, the symptoms start showing up.
I spent years trying to “push through” while my body was waving every red flag possible. When I finally stopped pushing and started looking for real answers, I found Functional Diagnostic Nutrition.
04
Functional testing finally showed me what was going on inside my body. Gut, hormone and food sensitivity testing were the missing pieces. It didn’t happen overnight. But little by little, my gut issues, my anxiety and pretty much every last symptom went away.
So when you tell me you’re exhausted, bloated, frustrated and done guessing... I don’t just understand it. I’ve lived it. And I know how much better life feels on the other side... I’d love to help you get there, too.
My personal journey is what led me here — and why I’m so passionate about helping women get real answers about what’s going on inside their bodies.
But it wasn’t just my story. After coaching women since 2011, I kept seeing the same pattern. Some of my clients had the basics dialed in: nutrition, water, sleep, stress and movement. They were doing the work. And they were still stuck with gut issues, hormone symptoms or a metabolism that wouldn’t move.
For those women, nutrition and lifestyle coaching alone weren’t enough. I wanted a way to help them go deeper.
So in 2025, I earned my Functional Diagnostic Nutrition Practitioner [FDNP] certification. Now I combine more than a decade of coaching with functional lab testing and my background in psychology and behavior change. Because knowing what to do is only half the battle. Actually doing it, week after week, is where most plans fall apart... and that’s where I come in.

“Anytime I’ve had a question or concern, Kenzie has been right there with information, guidance, or simply the encouragement I needed to keep going. I never felt like I was doing this alone.”
“Kenzie was always very positive yet would tell me when I needed to change something to get the results I wanted.”
“Kenzie has been wonderful—understanding, supportive and quick to offer thoughtful recommendations to help improve my symptoms.”
“I can’t say enough about Kenzie’s coaching calls and the guidance she provides along the way.”
“This has been the best experience, finding someone who I feel really listened, wanted to help and checked in on me over the last few months.”
“The difference with her is she emphasized reducing stress instead of just working out more.”

The goal isn’t perfect [ironic, coming from a perfectionist]. It’s clarity, a strategy and support, so you feel strong, confident and in control of your health again.

God is in everything I do.
Family comes first. Period.
No BS. Straight-shooter. Don’t ask me to sugarcoat it — I won’t [...but I’ll also be your biggest cheerleader].
Hard times build strong women.
Hot, Healthy + Happy > Skinny
Build what lasts — habits, memories, businesses, results.
Impact matters. I want every client, every program I create and every conversation I have to leave people better than I found them.
I don’t do things for the money… If it doesn’t make me happy, I’m out.
Zero tolerance for gluten, gossip or drama.
Excuses don’t burn calories. Do the damn work.
Fitness isn’t my life. It makes the rest of life better. [But yes... 10K steps is non-negotiable.]
Collaboration over competition. I compete with no one but myself.
Caffeine, sushi, date nights and beach vacations will always be part of my plan.
These are my people. My husband, Jay, has been right by my side through every chapter... the dance studios, the gyms, the hardest years and everything since. And our two busy teenagers, Cam and Brooks, are my biggest motivation.
Taking care of my health means I get to show up for them. Present, energized and actually enjoying this crazy, busy life. That’s what I want for you, too.
